UNITED STATES CHARLES ANSELM, OF NEW YORK, N. Y.

HEATER FOR BOTTLES AND THE LIKE.

Application led October 4, 1919. Serial No. 328,405.

To all whom t may concern.'

Be it known that I, CHARLES ANsELM, residing at New York, in the countyand State of New York, have invented certain new and useful Improvementsin Heaters for Bottles and the llke, of which the following is aspecification.

This invention relates to an improvement in electric heating devices,adapted for attachment to receptacles, such as bottles, hot water ba s,and the like, and one of the objects of t e invention is to provide adevice of the above type, which may be readily attached to an electricli ht socket or the like.

A further object o? the invention is to provide a device of the abovetype, which is simple in construction, compact, enabling it to be easilcarried or transported, and which is a apted for instant use whereverand whenever required.

Other objects and aims of the invention more or less specific than thosereferred to above, will be in part obvious and in part pointed out inthe course of the following description of the elements, combinations,arrangements of parts and applications of principles, constituting theinvention; and the scope of protection contemplated will be indicated inthe appended claims.

In the accompanying drawing, wherein I have illustrated a preferred formof embodiment of my invention:

Figure 1 is a vertical sectional view, showing my improved heaterattached to a bottle; and

Figure 2 is an elevational view thereof.

Referring now to the drawing, wherein similar reference characters referto similar parts in both views thereof, the reference numeral 1 denotesthe bod portion of the device, which is preferab y formed of a moldableinsulating material, such for instance as hard rubber, or any one of thevarious moldable insulating compounds now in eneral use.

rEhe body portion l is provided with a tapered or conically formed part2, which is adapted to enter the neck of a bottle, hot Water bag, or thelike, the tapered construction enabling it to form a closure forreceptacles having necks of various sizes.

Seated in a socket 3, formed in the lower end of the body portion 1, isa tubular member 4, which is preferabl formed of an insulating materialcapab e of withstanding a high degree of heat, such for instance asasbestos, mica` or the like.` This tubular member 4 forms a core for acoil of resistance wire 5, the lower end 6 of which is connected with arod or heavier wire 7 which extends through the tubular member 4,through the body portion 1. and provided with an ex osed terminal 8 atthe upper end of said body portion 1.

The opposite end 9 of the resistance Wire is connected with a wire 10,which extends through the body portion 1A` and is attached to a threadedcollar 11. positioned upon the cylindricallv formed end 12 of said bodyportion. e terminal 8 and collar 11, correspond in shape and form to theterminal portions of an ordinary electric light bulb, so that the devicemay be threaded into correspondingly formed sockets.

Threaded upon the lower extremity of the body portion 1 is a metalliccasing 13, which completely encloses the resistance wire, and itsconnections, and -forms a liquid proof closure member therefor.

Threaded upon an enlarged portion 14 of the body 1 is a plate 15 havinga plurality of downwardly extending spring arms 16, the lower end 17 ofeach being adapted to engage the neck of the bottle underneath the usuallip 18 thereof, whereby the device may be readily attached to thereceptacle to be heated.

The manner of utilizing my improved heater will be obvious from aninspection of the drawing, for it will be seen that with the deviceinserted within the neck of a bottle, as shown, and the electricalconnection made with the source of supply, the heat generated by theresista-nce wire 5, will be communicated to the metallic casing 13, andthe latter being in contact with the liquid contents of the bottle, willOperate to heat the same.

In Figure 2 of the drawing I have shown a. cap 19 threaded upon theenlarged portion 14 of the body portion 1. This cap, it will be noted,forms a cover for the device to protect the electrical connections, andalso when detached forms a small cup from which the liquid contents ofthe receptacle can be drunk.

It will accordingly be seen that I have provided a device well adaptedto attain, among others, all the ends and objects above pointed out, inan exceedingly simple yet eicient manner.

The device will be found especially useful for heating receptacle, suchas nursing bottles or the like, enabling a traveller to readily utilizethe device wherever there is installed an incandescent lighting system.It is also most useful in other relations and for other purposes.

As many changes could be made in this construction without departing'from the scope of the following claims, it is intended that all mattercontained in the above description or shown in the accompanying drawingshall be interpreted as illustrative only and not in a. limiting sense.

Having `thus described my invention what I claim as new and desire tosecure by Letters Patent is:

l. A device of the class described, comprising a body portion, one endof which is provided with terminals adapting it to be attached to anordinary incandescent lamp socket, and the opposite end with an electricheating device adapted to be inserted within the neck of the bottle orother receptacle, and spring means for detachably clamping said deviceto a bottle or other receptacle.

2. In a device of the class described, in combination, a body portion,terminals carried upon one end of said body portion adapting said deviceto be attached to an electric lamp socket, a depending hollow metalliccasing carried by the opposite end of said body portion, adapted to beinserted within the neck of a bottle or other receptacle, a core ofinsulating material located within said casing, a heating coil locatedupon said core, said body portion being provided with a part adapted toform a clos-ure with the neck of a receptacle, and a spring clampingmember for fastening said device upon said receptacle.

3. In a device of the class described, a body portion having acone-shaped part adapting it to be adjustably secured to the neck of areceptacle, one end of said body portion being provided with terminalmembers adapting it to be attached to an electric lamp socket, a hollowmetallic .casing secured to the -opposite end of said body portion, saidcasing bein adapted to be inserted within the neck o a bottle or otherreceptacle, a core formed of insulating high heat resisting materiallocated'within said casing, a heating coil provided upon said core,connections between said heating coil and said terminals, and resilientmeans for attaching said device to the neck of a bottle or otherreceptacle.

4. A device of the class described, comprising in" combination a bodymember provided with a plurality of threaded portions, one of saidthreaded portions being adapted for attachment with a lamp socket, aspring clamping member mounted upon the other of said threaded portions,aidepending hol low metallic casing carried by theopposite end of saidbody portion, adapted to be inserted within the neck of a bottle orother receptacle, heating means within said cas]- ing, and said bodymember being provided at its intermediate portionwith a cone-shaped partadapting it to be adjustly secured to the neck of a receptacle.

In testimony whereof I aiiix my signature in the presence of twowitnesses.

CHARLES ANSELM.
